What does hail actually cost you? Estimate the avoidable loss

In short. Hail netting is bought to avoid losses, so the right starting number is not the price of the net: it is the crop value one damaging storm destroys. Enter your own crop value, area and hail frequency, and the estimator shows the expected annual loss and what protection could save under assumptions you control. It never invents a product price; you compare the result against a documented quote.

Your own number: expected gross revenue per acre or hectare for the protected crop.

From your loss history or insurance records.

Hail damage ranges from cosmetic scarring to total loss; use your experience.

An assumption you control, not a promise: effectiveness depends on netting, installation and storm.

UMN Extension reports at least 10 years with proper use and storage.

How the estimate is calculated

  • Value at risk per event = area x crop value per unit x average loss per event.
  • Expected annual loss = value at risk per event divided by years between events.
  • Avoidable annual loss = expected annual loss x assumed damage reduction.
  • Avoidable loss over service life = avoidable annual loss x netting service life.

Every input is yours: the estimator applies arithmetic, not hidden assumptions. That is deliberate. A tool that guessed your crop value or hail risk would produce a confident-looking number that means nothing.

When hail netting makes sense, and when it does not

The economics work when the avoidable loss over the netting's life clearly exceeds the delivered cost of the system, including installation labour. High-value crops (orchards, vineyards, berries) in hail-prone regions reach that threshold quickly. Low-value field crops in low-hail regions usually do not, and we say so rather than selling netting that does not pay for itself. If your result looks marginal, request the quote anyway: the comparison costs nothing and settles the question with real numbers.

Frequently asked questions

Does this tool tell me what hail netting costs?

No, deliberately. Netting cost depends on your dimensions, mesh, treatment and delivery terms, so a generic price would mislead you. The estimator quantifies the other side of the decision: the crop value a damaging hail event puts at risk. Request a documented quote and compare the two numbers yourself.

How effective is hail netting at preventing damage?

It depends on the netting, the installation and the storm, which is why the estimator makes protection effectiveness an assumption you control rather than a promise. As context, University of Minnesota Extension describes hail netting as a reasonable alternative to hail insurance, and a 2023 Journal of Economic Entomology study in a commercial orchard also measured 94 to 96 percent exclusion of key insect pests with draped netting.

How long does hail netting last?

University of Minnesota Extension reports that with proper use and indoor storage on spools, hail nets can be re-used annually for at least 10 years. Our catalogue anti-hail netting is UV-treated HDPE; the quote states the specification and its assumptions.

How do I estimate my hail frequency?

Use your own loss history or your crop insurance records: how many years out of the last ten did hail cause meaningful damage? County-level hail climatology from NOAA storm reports can also help. The estimator lets you test optimistic and pessimistic frequencies in seconds.
